MACHINE FORl MAKING CORRUGATED BOARD.

Application filed August .1.8, 1919.

T all 'whom it' may concern.'

Be it known that I, BERG HniNnIcHs, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Machines for Making Corrugated Board, of which the following is a full, clear, and exact description.

The invention relates to machines for making corrugated hoard and more particularly to the mechanism employed for cutting the continuous Web into sheets of the desired size.

The object of the invention is to provide an improved cutting mechanism adapted to sever the sheets from the web which is readily adjustable to adapt it to successively cut sheets of different lengths.

A further object of the invention is to provide improved cutting mechanism in Which the cutters are mounted on a carriage which is adapted .to move With the web and which is operative by a spring or yielding connection which causes the cutters to grip the Web and keepy it under a slight pressure, during the cutting operation, for the purpose. of preventing any buckle. in the Web. Another object of the invention is to provide simple means for automatically stacking the severed sheets.

Other objects of the invention Will be apparent from the specification.

The invention consists in the several novel features hereinafter set forth and more par-- ticularly defined by claims at the conclusion hereof.

The machine comprises a frame 9 which may be of any suitable construction and in Which are mounted in cooperative relation the rolls 10 Which may, he the final rollsacting on or for feeding the corrugated board. These rolls are continuously driven synchronously with the machine for corrugating the Web and applying the facing sheet or sheets thereto, so that the surface-speed of these rolls Will correspond to the travel of the finished Web. These rolls are coactively driven by gears 11, one of Which Will be driven by suitable mechanism from the driving mechanism of the machine for making the corrugated board or by other mechanism driven in synchronism with the machine.

A gear-Wheel 12, fixed to the shaft of the lower roll 10, meshes with a pinion 13 on a shaft 14 Which is mounted in bearings 15 on the frame 9. A sprocket Wheel 16v on the shaft 14, a chain 17, driven by saidis rocket, and a sprocket 18, fixed t0 a clutch-W eel 19, serve to drive said Wheel continuously While the corrugated board machine is in opera.- tion. Wheel 19 constitutes the continuously driven member of a clutch, the operation of which is controlled by the Web, for intermittently operating the cutter mechanism. Wheel 19 is loose on a shaft 20 and serves to drive said shaft through a pair of dogs 21 Which are pivoted, as at 22, in a collar 23 fixed to said shaft. Springs 24, connected to said arms Arespectively and to posts 25 on said collar, serve to normally pull the arms into engagement with the internal frictionface 26 of the wheel 19. An equalizing bar 27 is connected to the dogs by links 28. This bar causes the dogs to be conjointly shifted into or out of engagement with the clutch Wheel 19. A trip pin 29 is tiXed to one of the dogs and is adapted to be caught by a notch 30 in a bar 31 Which has its lower end pivoted to the frame, `as 32. In operation, when the pin 29 passes into the notch 8O and is arrested by'step-'b'ar 81, both of the dogs Will, through the equalizer bar 27, be held against rotation 'and disengaged from the clutch Wheel 19. When the 'stop bar 31 is Withdrawn from the path of pin 29, springs 24 will draw the dogs into operative engagement With the friction face 26 of the clutch Wheel 19 and cause the shaft 20 to be driven. The stop-notch and trip-pin 29 are adapted to arrest the shaft at but one point, so that upon each operation of the stop-bar the Shaft 20 Will make one complete revolution.

The invention contemplates controlling` the clutch tor operating the cutter mechanism, by the web ot paper, and for this purpose, a controller-arm 33 is pivoted, as :it 34, in a bracket 35 held on a bar 36 which is suitably secured to the trame, This arm is adapted to be engaged and shifted by the front edge ot' the Web and when the arm is rocked about its pivot its lov-:er end Will engage a collar 37 which is Vfixed on a releasor-bar 3S that is slidably mounted in roller-guides 39 which are suitably sustained by the frame-Work ot the machine. rThe inner end ot bar is pivoted, as at 40U to the clutch-stop 3l. As a result, when the front edge ot the Web engages a d shifts the dog 33, the stop-bar 3l will be operated to release pin 29 and render operative the clutch for driving the c ttingi` mechanism. To adapt the controlling' mechanism for dit ferent lengths of sheets, bracket 35, in Whicl arm 33 is pivoted, is slidably adjustable on the bar 36 and is adapted to be conveniently secured in assigned position alone' said bar by cam-lever 42. This clutch and controllin mechanism exemplify a start and stop mechanism for the cutter-driving mechanism which is controlled by the end ot the iveb. Also one in which the controlling` mechanism ris adjustable so that it can be quickly set to sever sheets of different lengths trom the continuously fed Web by shifting the arm 33 Which is operated by the end of the web.

The cutter-mechanism comprises a carriage 44 which is slidably mounted on the frame 9 and comprises a bed 45, over which the web is ted by rollers l0. ik cutter 46 is secured to the front end ot the bed and a rotary cutter 47 is secured to a mutilated roller 4S which is mounted to rotate in bearings 49 on the carriage 44, mally, when the cutter-mechanisui is at rest, the cutters are in the relative position shown in Fig. 3, so that the web will be tree to pass between them until the rotary lcutter is operated toward the cutter 46. A sprocket 50 on the clutch-shaft 2() drives a chain 5l which operates a sprocket 52 on a crossshaft 53 which is mounted in fixed bearings 54. Crank-disks 55 are secured tothe ends of shaft respectively. This driving connection for the shaft 53 serves to operate this shaft a complete revolution every time that the clutch is rendered operative. Disks rserve to reciprocate the cutter-carriage 44 by? means of links 56 which are pivoted, as at 57, to the crank-disks, and, as at 38, to bars 59, which are held on the sides oi the carriage 44 bev bolts 60`r Which pass through slots 6l in said bars and permit movement of the bars relatively to the riage. rllhe bars operate the carriafe Northrough yielding` connections wnsistiiu;4 ot rods 62 which are lixed to the bars 59 respectively and pass and slide through guides 623 which are l'ixed to the carriage 44, and springs 64 which are engaged by members 65 on the rear end ot rods 6L so that ther 9 power applied to the bars 59 will be yieldingly applied to the carriage during; its torivard movement. uringij retraction ot the carriage,l a shoulder 59 on each bar 59 will engage guide 63 and positively shift the aarriage. ril`he rotary cutter-roll 43 has atiixed to one oi its ends an arm 66 which is counected to one ot the links 56 by a short vertical link 6'?. T he rertical movement ot this link 67 operates the cutter-roll 46 to which the rotary cutter 47 is secured during the advance ot the cutter-carriage. A characteristic ot this construction is that the yielding connection makes it. possible to operate the carriage at a slightly differential with respect to, or greater speed than, the web. so that when the latter is gripped between the cutters, the yielding connections `will permit the cutters to grip the corrugated i board and keep it under a slight tension.

As soon as the sheet is cut from the web.y during` the advance ot the carriage` the carriage Will be tree to be moved away trom the end of the web bythe torce ot the springs 64. This will cause the rotary cutter to keep clear of the end ot the Web until the latter has been rocked upwardly sutticiently to permit the Web to pass under it.

An abutment 7() ou member 65 ot one ot the yielding connections (Fig. 3") is adapted to retract the stop-bar 3l and the releasorbar 38 to restore the controller dog 33 to its normal position at the end ot the outstroke ot the cutter-carriage.

That portion of the web which projects beyond the cutter-roll is supported at one side by a rail 75, whilst its other side unsupported, fr rail is supported ou legis 76 and an inclined support 77, ronsisting; ot rails between legs 76 and h; ie-boards 7S, is disposed to catch the sheets utter they have been severed from the webA the sheets talling by gravity onto said support and torming` a stack. means t'or automatically stacking; the sheets as they are cut trom the Web.

In operation, the finished corrugated web will be ted continuously 'from the rolls 'l0 and when its iront edge engages the coutroller-arm 33` the latter `will operate the releasor-har 38 to shi t the stop-bar 3l and release the trip-pin ot the clutch. Thereupon, the clutch Will become operative to drive shat't 53 and the crank-disks 55 on shaft 53 one revolution. These disks, through links 56, Will operate bars 59 to reciprocate the carriage through the yielding connections and simultaneously the rotary cutter will be operated by means ol arm 66 This appliance exemplifies lle Lacasse and link 67 so that a sheet will be severed from the web during the initial portion of the forward stroke of the carriage. After the sheet has been cut, it will be Without support, except at one side of the rail 75, so that its other side will fall by gravity and'build up a stack on the inclined support 77. As the carriage approaches the en d of its outstroke, abutment 70 Will strike the stop-arm 3l, so that thc trip-pin 29 ivill be arrested by the notch 30 in said arm, vwhen the clutch-shaft has made one complete revolution, so that the cutter-carriage will be arrested at the starting point and rer-nain idle until the front edge of the web again contacts With the controller arm 33 to start the cutter-mechanism as before and repeat the cutting operation. Obviously, by adjusting the controller arm 33 and collar 3T, which is adjustable on rod 38, so that the arm will be engaged by the edge of the Web When diiferent lengths thereof have been projected beyond the cutters. the length of the sheets may be varied as desired Without varyingthe operation of any of the cuttermechanism or any other change, except said adjustment.

The invention exemplifies improved intermittently operated cutter mechanism under control of a device which is operable by the edge of the iveb so that the lengths of the sheets may be varied as desired. Also mechanism in which the reciprocating cutter mechanism is operated by a yielding connection so that it is not necessary to operate the carriage and the Web in strict synchronism. to avoid buckling of the Web. Also cutter mechanism which is operable in conjunction with means for automatically stacking the severed sheets by gravity.

The invention is notl to be understood as restricted to the details set forth, since these may be modified Within the scope of the appended claims, without departing from the spirit and scope of the invention,
